What happened
Türkiye’s Energy Market Regulatory Authority, known as EPDK, has set the electricity transmission surcharge applicable in 2027. The charge will be 0.7% of the transmission tariff of Türkiye Elektrik İletim AŞ (TEİAŞ), the country’s electricity transmission company.
The EPDK board decision was published in the Official Gazette, according to Enerji Günlüğü. It becomes effective on 1 January 2027.
The decision also establishes the administrative process for the charge. TEİAŞ is required to work out the surcharge on a monthly basis. It must then deposit the relevant sum into EPDK’s account no later than the 25th day of the next month.
Why it matters
The ruling fixes a defined component of the 2027 transmission-tariff arrangements. For TEİAŞ, it provides both the percentage to use and the timetable for calculating and remitting the charge.
Companies monitoring electricity-market costs in Türkiye can now identify the rate that will apply to this transmission-related surcharge during 2027. The published material does not explain how, or whether, the amount will be passed through to particular end-user bills, supply agreements or other commercial arrangements.
The monthly calculation requirement means the process will recur throughout the year rather than being settled in one annual payment. The following-month deadline sets the point by which each monthly amount must reach the regulator.
What readers should do next
Energy, finance and procurement teams with exposure to Turkish transmission charges should incorporate the 0.7% rate into their 2027 monitoring and budgeting assumptions where relevant. They should also distinguish the stated regulatory surcharge from any separate tariff, billing or contractual treatment, which is not detailed in the available decision summary.
TEİAŞ’s operational cycle starts when the decision comes into force at the beginning of 2027. Each month’s calculation will be followed by a payment obligation due by the 25th of the month after that calculation period.
